Presentation
Incidental finding. Unrelated history of ischemic heart disease, chronic kidney disease, presenting with cardiac failure.
Patient Data

Features consistent with a septated gallbladder, with multiple septa splitting the gallbladder lumen. The gallbladder is otherwise normal.
Case Discussion
Typical appearance of a multiseptated gallbladder. This is a rare congenital appearance of the gallbladder due to multiple septa splitting the lumen.
Single septa oriented longitudinally give rise to a "bi-lobed" gallbladder while oriented transverse or obliquely give rise to an "hourglass" gallbladder 1. The compartmentalisation of the gallbladder may lead to increased bile stasis, predisposing to cholelithiasis and cholecystitis 1. In this instance, the patient has no significant current or past history of biliary colic and remains completely asymptomatic.
The differential diagnoses include:
duplicated gallbladder
gallbladder diverticulum
gallbladder fold(s)
Phrygian cap
choledochal cyst
